Method Detail

getDefaultParameters

java.util.List<IStrategyParameter> getDefaultParameters(java.io.File file)
                                                 throws java.io.IOException,
                                                        JFException

Returns default strategy parameters

Parameters:

file - a compiled strategy .jfx file

Returns:

strategy parameters

Throws:

java.io.IOException - in case of file read/load error

JFException - if security-related exception occurs

compileStrategy

java.io.File compileStrategy(java.io.File srcFile)

Compiles a strategy .java source file to a .jfx file

Parameters:

srcFile - source file

Returns:

the compiled .jfx file

startStrategy

java.util.concurrent.Future<IStrategyResponse<java.util.UUID>> startStrategy(java.io.File strategyFile)
                                                                      throws java.io.IOException

Starts a strategy with default parameters.

 // start a strategy without fetching the id
 strategyManager.startStrategy(jfxFile);

 // start and fetch the id
 IStrategyResponse <UUID> startResponse = strategyManager.startStrategy(jfxFile).get();
 if (startResponse.isError()) {
     System.err.println("Strategy failed to start: " + startResponse.getErrorMessage());
 } else {
     myStrategyId = startResponse.getResult();
     System.out.println("Strategy successfully started: " + myStrategyId);
 }
 

Parameters:

strategyFile - strategy jfx file to run

Returns:

returns Future object for obtaining the server response

Throws:

java.io.IOException - in case of strategyFile read/load error

startStrategy

java.util.concurrent.Future<IStrategyResponse<java.util.UUID>> startStrategy(java.io.File strategyFile,
                                                                             java.lang.Object[] params)
                                                                      throws java.io.IOException,
                                                                             JFException

Starts a strategy with parameters. Note that the parameter array size should match the strategy public Configurable field count, likewise the value types should match.

 // start a strategy without fetching the id
 strategyManager.startStrategy(jfxFile, new Object[]{"param value", 1, "another param value"});

 // start and fetch the id
 IStrategyResponse <UUID> startResponse = strategyManager.startStrategy(jfxFile, new Object[]{"param value", 1, "another param value"}).get();
 if (startResponse.isError()) {
     System.err.println("Strategy failed to start: " + startResponse.getErrorMessage());
 } else {
     myStrategyId = startResponse.getResult();
     System.out.println("Strategy successfully started: " + myStrategyId);
 }
 

Parameters:

strategyFile - strategy jfx file to run

params - strategy parameters

Returns:

returns Future object for obtaining the server response

Throws:

java.io.IOException - in case of strategyFile read/load error

JFException - in case of parameter error, i.e., incorrect array size or wrong value type.
